我们应该问...... [英] should we ask the ..

问题描述

我们应该询问用户的项目名称，代码，价格，数量并将其显示为表格吗？

should we ask the item name , code, price , quantity from user and display it like a table?

推荐答案

我将您的问题解释为如何询问...。在这种情况下，您最好先做一些伪代码方法，以便决定要完成的任务。然后开始用实际语言实现 - 在这种情况下为C.

可能的方法是：

I interpret your question as "How to ask...". In this case, you best do some pseudo-code approach first to make up your mind on the task to do. Then start to implement in the actual language - C in this case.
A possible approach was:

1. read all entries into list or an array
2. display the read data as table

读取所有条目可能是这样的：

Reading all entries might be something like this:

define an entry as a record (or struct in C) with elements:
- name     --> e.g. as fixed size array of characters
- code     --> e.g. as fixed size array of characters
- price    --> e.g. as C double value
           --> or as unsigned int value of the smallest currency unit
- quantity --> e.g. as unsigned int value

define the list of records as a fixed size array of entries (array[0...N-1])
--> this is the simplest approach in C

max number of entries = number of reserved entries in the array (= N)
current record index = 0
while (current record index < max number of entries) loop
    if (read record(array[current record index])) then
        increment current record index
    else
        break loop
    end if
end loop
number of read records = current record index + 1

以表格格式写入记录可能是

Writing the records in tabular format might be

write title row
current record index = 0
while (current record index < number of read records) loop
    write data row for array[current record index]
    increment current record index
end loop

转换为C留作练习。

Transforming into C is left as exercise.
